have e maximum drgreeol strength.V This result l Lceomphsh y proper dis" 'ioution of the metal, and peeiully b v having the top tension members .lispvsedl substantially Wholly over the diaphragme or beams ol the bolster, the latter being transversely counected together by a number ol tie bars which, if desired, may rest in recesses or seats on the top .surfaces ofthe beams or diaphragnis. instead of having a single plate or bar com pressionniember o n the under side ot' the cross-bearer or transom., l employ two such plates or bars and overlap them beneath the center sills whereby it one portion ol the cross-bearer becomes damaged or injured it is onlT necessary to remove one ol.' the compression plates to ell'ect repairs.

l lieve illustrated my preferred embodiment oi the invention on the accompanying drawings forn'ling a part of this specii'ieation.

On said drawings Figure lis s, vertical cross-section oll a box ear embody: ig my in- 35 vcntion; Fig. 2 is a side elevation of one of the cross-bearers or llying transoins showing the center and side sills in section; Fig, 3 is-a longitudinal vertical section of a portion of the car outside ol' and adjacent to thc conter sills; Fig. fl is :i fragmentary longitudine] vertical section adjacent to one of the side sills; Fig. 5 is e cross-section of a detail o `construe-tion; and Fig. is perspective o View of my improvml forni oiu body-bolster. Referrincf to the d rawinffs it will be noticed that the car under"arne includes a pair ol channel conter sills l0, 10 spaced apart end disposed with their lla-nges extended outwardly. The underllraine also includes. the 30 channel side sills il, l1 with their flanges projected outwardly. 'The body' bolster comprises a pair of tapered beams or d1shshaped diaphragme 12, l2 on cach side of the ccutcrsi'lls', each beam l2 having a top flange 5 13 provided with e number of transverse re- Specification ol Letters Estone.

Gosses or seats 11i on its upper fece, three resented to, :ieeeu 'Serial No. 370,5333.

'(3) of suoli sests being provided for each boem in the present instance. @n its lower edge eech beam or diaphragm has en inclined flange 15, the boem :it its inner and outer ends .homing flanges 15 and 17 respectively riveted to the Webs of the center sill and side sill respectively.` l provide s. single breed compression plate 1S r've-ted to the flanges l5 of all of the beams and extended beyond the ends of the beams so es to underlie .find be riveted to the lower flanges ol' the side sills 11, as is clearly iudicated in l.

Along the top` of the body-'bolster I provide two (2) tension bars .1.9 of substantial thickness, each being located above and-riveted to the top flange 13 ol one of the beams 12 ou each side of the center sills, the Webs -ol the letterbeing ejfiertured or slotted to diaphragm 2l. w

accommodate the bars i9 which extend sub- 7 stantially the lull length of thebolster. In order to brace the bolster transversely and tio the beams 12 together7 provide a plurality of bars 2O which rest in. the seats 14 and are riveted to the lianges 13l end to the bars ll), as is clearly shown in Fig. 6. Between the center sills l empio)r a, spreader Orhieh is provided With a king pin socket 22 and is riveted to the Webs of the center sills, to bars/19, and to longitudinal angle bars 23 extending along the inner surlaces ot' the lower marginal edges of the center sills. lt will be noticed that by using bars 19 oli substantial cross section vthe` strains ou these top tension bars are limited to the planes of the beams or diaphragme l2, by which construction l am permitted to use a minimum amount of metal to secure the 'requisite strength. l iind that the tie bars 2() are sullicientlvstrong to' maintain the beams or diaphrsgins 12 in piece and 'to stillen end strengthen the bolster trans"v verselji For the erossbesrers or needle beams employ a construction like that shown in Fig. 2 wherein a p'sir of beams or displnagrns 2li have their inner end flanges riveted to the Webs of the center sills l0, l() and their outer end flanges riveted to the Webs of the chan nel side sills lll ll. Thev webs of the center sills on a level with the tops of' the beams 24 are apertured or provided with holes through which )asses e `tension bar 25 extentie i troni side sill to side sill and riveted to tn top nilanges of the beams 24. lnstesd of a, 110

lill@ single bottom compression plate riveted to the lower flanges of the beams 24, I prefer to use two (2) suchcompression lates or mem bers 26 and 27, each of whici is riveted to the lower flange of one of the beams 24C, the inner ends of the plates 26 'and 27 being .overla ped, as shown in Fig. 2, and riveted not on y to each other but also tothe lower flanges of the center sills. Vitha construction ol cross-bearersor needle beams of this kind, it one portion or side thereof is damaged the injured diaphragm 24 may be y readily removed by taking oil or removing only one of the compression plates, whereby a saving ol time and cutting of rivets iselL fected. At the saine time my new form of compression member has great strength because of the secure fastening together of the twoparts and their riveting to the center sills. yli desired, the cha'iinel or dish-shaped beanie 24 may be strengthened by angle bars 428 and 29friveted along their edges, as shown -in Fig. 3. 'It is to be understood thatf'this overlapping feature of the compression plates may be used equally as advantageousl in the'bodybolster. 'f T is form of underlrame construction is suitable for use in cars of various kinds, but l have illustrated `my invention as embodied in a boit car, and in such a car the longitudinal Wooden stringere 30 rest upon the tension bars 19 of the body-bolster and upon the correspondingv parts of the other transverse underrame members.- `The outside stringere 30 however rest upon .the top flanges of the side sills 11, l1, and in order toretain them in place I use off-set brackets 31, shown in Fi 5, which are fastened tothe webs of the si esills and. to the inner faces oi the stringamv ers. 'lhe longitudinal metal late 32 is fas tened to the top flanges of t .e center sills, `and on top.of the same is placed another stringer or nailin strip 33, the licor 34 being fastened to the ongitudinal Wooden'nienn n bers, vas is clearly illustrated, and as will be readily understood.` l

To those skilled parent that man in the art it will be apchanges may'be made in the construetiin..v4 ereinA shown and described .Witlifoiitlparture from my invention. For example, the seats or recesses 14 of the beams 12 can be omitted, if desired, and thetiefbars 20 `caused to rest upon thetop laces of the upper flanges of the beam, or, if desireththe tie bars 20 may be located above the tension barslQ. l j;
